To aZZ 1072,0171, it may concern:

Be it known that I, THOMAS SHARP, a citizen of the United States,residing at Carlisle, in the county of Cumberland and State ofPennsylvania, have invented certain new and useful Improvements inLamp-Holders and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in heaters, and has particularreference to holders for lamps or like heat-generating devices which arecapable of collecting and directing the heat to certain points for useor application.

The invention comprises certain novel constructions, combinations, andarrangements of parts, as will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved lamp or heater holder. Fig. 2 is a vertical central sectionthrough the same. Fig. 3 is a horizon tal sectional view through thesaid holder, the inner lining being shown as having a curved form incross-section. Fig. 4. is a detail view, in front elevation, of thelower portion of said holder provided with an anchor or weight receivingcompartment.

My improved heat collecting and applying mechanism is adapted forreceiving a heatgenerating means, preferably an ordinary lamp, andcollecting the heat radiatingthera from in such a manner as to properlydirect it to any given point for use. While it will be understood thatthe holder may be supplied with any other heat-generating means asidefrom a lamp without departing from the spirit of the invention, yet Ipreferably use an ordinary lamp and have illustrated in the drawings thedevice as particularly adapted for receiving a lamp, and I will nowdescribe my invention, reference being had to said illustration.

The holder is formed with a casing 1, which is open on one side, theremaining sides and the top and bottom being closed. The bottom of theholder is formed with a broad base 2 to prevent the likelihood of theholder being easily tipped or knocked over, and the upper end 3 of thecasing is preferably curved from the back toward the open front for thepurpose of throwing the heat units collected in the holder upwardly andorwardly. The bottom of the casing is adapted to support a lamp of theusual and ordinary construction, the casing being made of ample helghtto accommodate the usual chimney and other POT? tions of the lamp. Animportant feature of the invention is the lining or shield 5 with whichthe holder is provided, and the said lining comprises walls spaced apartfrom the inner surface of the casing-walls 1, so as to leave anair-space between the said lining and the said casing. The saidair-space is left open at the top and bottom, as clearly shown in Figs.1 and 2 of the drawings.

I usually mount the lining 5 in the casing 1 by providing the same withtangs or attaching-brackets 7, which are secured at one end to thelining and at the other end to the said casing 1. Such tangs may besoldered or riveted to the adjacent parts, as found most desirable. Thelining 5 may be made angular in cross-section, so as to extend in planesparallel with the walls of the casing 1, as shown in Figs. 1 and 2, orthe said lining, as shown at 8 in Fig. 3, may be curved in crosssectionwithout departing in the least from the spirit of the invention. In eachcase an air-space is left between the lining and the casing, sothat airmay enter the said space at the bottom of the casing and pass upwardlyas it becomes heated and out at the top. The provision of the casingwith such a lining is found to add very materially to the effectivenessof the holder for collecting and directing heat units from the lamp orother heating agent placed in the holder. Without such a lining the heatradiating from the lamp is found to also radiate in a lateral directionfrom the casing to a large extent; but by using the lining with anair-space between it and the casing it is found that such radiation ofthe heat units thrown out by the lamp is prevented to a great eXtent,for the movement of the heated air upwardly in the space between thelining and the casing operates to intercept said radiation and to carrya-greater portion of the heat units upwardly to the top of the casing 1.

In connection with the casing and its lining I also employ a shield 9,which is hung in front of the lamp-flame to prevent the dis placement ofthe lamp by the contact of eX- ternal objects. The said shield orshutter 9 is removably mounted in position, being provided withsuspending-hooks 10, which are adapted to engage eyes 11, formed eitherupon the lining 5 or the casing 1, as preferred. The shield 9 is thussuspended in position by bringing the hooks into engagement with theeyes .11 The shield can be readily removed by lifting the same asufiicient distance to disengage the hooks from said eyes. Since an openspace is left below the shield, as well as above the same, the heatedair collecting around the lamp will be carried'upwardly to the top ofthe lamp-holder in the same manner as described with respect to theheated air which passes between the lining 5 and the casing 1.

To further make it possible to collect and direct the heat unitsgenerated by the lamp or other heat agent, the casing 1 is also providedwith an outer collecting hood or cap, as 12. This hood is made largerthan the casing at the top and is formed with a curved upper surface, sothat an air-space may be left at 13 between the topof the casing and thesaid hood. The hood is preferably supported upon the casing by means ofbrackets or tan s 14, which are secured. to the lower edge of the hoodand extend inwardly therefrom to the casing 1, where they are alsosecured in place. Corner-brackets and attaching-tangs 15 may also beprovided which extend, preferably, in any inclined direction from thecorners of the hood to the corners of the casing 1, as illustrated inFigs. 1 and 2. The space between the hood and the casing is thus leftopen at the lower edge of the hood, so that heat units escaping throughthe casing 1 may be collected and passed upwardly between the saidcasing and hood. The exit of course for such heated air is at the front,where the space between the hood and the easing is also left open.

I find that the efficiency of the holder as a heat collector anddirector is also improved by securing asbestos or other similar materialto the outer surface of the casing 1,-as at 16, and such asbestoscovering may also be secured to the inner surface of the hood 12, asshown at 17. The asbestos, because of its non-heat-conductingproperties, serves to prevent the escape of many heat units through thetop of the holder. A suitable carryinghandle 18 may also be provided forthe car rier, the said handle being pivotally secured to the side of thecasing or to the hood, as

preferred. The handle is made sufficiently long to extend above thecasing when it is used for lifting the holder, and of course the saidhandle may be folded downwardly against the back of the casing when theholder is not being carried from place to place. The holder may beprovided with an anchorreceiving receptacle at its lower end. 19, asshown in Fig. 4, if preferred, and in this instance a shield 20 isprovided, upon which the lamp or heater may be supported. The receptacle19 is of suitable size to receive weights of any kind, and one or moreordinary bricks may be placed therein for adding stability to the heaterand preventing its accidental tipping.

It will be apparent that other minor details in the construction of theholder may be varied within the spirit of the invention.

In using the heater it may be employed for furnishing heat to a room, orpreferably to a person who is suitably covered.

The heater may be placed at the back of a chair, with the open sideturned toward the chair, and the person to be heated or kept comfortableis then seated upon the chair and may be covered with a blanket or othercovering material, so as to hold the heat about the body of the person.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a lamp-holder, a casing open at one side, and proportioned toaccommodate a lamp, a shield interposed between the lamp and casing andstopping short of both the top and the bottom of the casing, anddefining a space, a top curved toward the open side, and a curved hoodspaced from the curved top and the sides.

2. In a lamp-holder, a casing open at one side, and proportioned toaccommodate a lamp, a shield. interposed between the lamp and casing andstopping short of both the top and the bottom of the casing and defininga space, a top curved toward the open side, and a curved hood spacedvfrom the curved top and the sides and rising from the point adj acentthe top of the shield.

3. In a lamp-holder, a casing open at one side and proportioned toaccommodate a lamp and provided with an anchor-receiving recess, ashield interposed between the lam and casing and stopping short of boththe top and the bottom of the casing and defining a space, a top curvedtoward the open side, and a curved hood spaced from the curved top andsides.
